GRAIN-CAR DOOR.

SFEGIFICATION forming part of Letters Patent No. 693,979, dated February 25, 1902. Application filed August 19, 1901 Serial No. 72,487. (No model.)

Too/ll whom, it may concern.-

Be it known that I, J OHN MONTGOMERY, a subject of the King of Great Britain, residing at Simcoe, county of Norfolk, Province of Ontario, Canada, haveinvented a certain new and useful Improvement in Grain-Oar Doors; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a partof this specification.

This invention relates to grain-car doors, and has for its object an improved door which can be swung either to the outside or the inside of the car or can be lifted on slides from the bottom to the upper part of the doorway,

so as to leave a clear opening underneath it.

The door fills the lower half of the doorway and is arrangedto bear against the inside of the door-post at the hinge end of the door, and a sliding bolt or leaf which extends from the top to the bottom of the door is arranged to engage the inside of the door-post at the free end of the door.

The door may be swung inside or against the side of the car either when itis down and in its lowermost position or when it is raised. It may also be swung out, so that the free end of the door swings entirely around against the side of the car when either in its lowermost or its uppermost position.

In the drawings, Figure l is a side elevation of the door in its closed position. Fig. 2 is a horizontal longitudinal section showing the door closed. Fig. 3 is a horizontal longitudinal section showing the door swung partly in. Fig. 4 is a detail of the hinge and of the connection between the hige and the vertical rod on which the door slides. Fig. 5 is a horizontal longitudinal section, on an enlarged scale, showing the lever employed to actuate the locking device. Fig. 6 shows a pin over the front of the door.

2 indicates a vertical rod secured in a socket 3, that is made fast to the bottom of the car. The rod 2 is secured at its upper end bya screw which passes through an eye 4.

5 indicates a tube about half as long as the bar 2 and arranged to slide vertically thereon. The tube 5 surrounds the rod 2 and slides on it.

door 8 to the tube on the rod 2.

6 and 7 are the hinges employed to hold the Each hinge is made with two leaves 6 and 7, held on a pintle 9. The leaf 6 is secured to the tube 5 and is capable of turning with the tube 5 on the rod 2. ranged to be secured by bolts or screws to the door 8. The apex of the angled part of the leaf 7 is set in front of the extreme rear of the door 8, anda notch 10 is out in the door to enable the leaf 6 to turn on the pin 9 toa position such that the leaf 6 and the branch 11 of the leaf 7 will lie parallel and the rod 2 and the tube 5 will be at one side of the body of the door and the branch 12 of the leaf 7 will be on the opposite side of the door.

The described position is shown in Fig. 2.

The bar 2 is erected inside the car behind the post 13, leaving a space between it and the post sufficient for thereceptionof the end of the door 8. g r

The door 8 is made of a length such that when the end of the door is in place between the post 13 and the bar 2, with the hingeleaf 6 bearing closely against the post, the free end of the door will just clear the post 14, enabling the door to be swung past the post 14 to the outside of the car.

On the front or the outside of the door 8 is a sliding plate 16, held by bolts which pass Theleaf 7 is bent at an angle and is arnotch are preferably lined with some metallie bearin g material, as 20. (Shown in Fig. 5.)

The lever 18 is arranged to force the sliding plate 16 in either direction and is especially arranged to force it strongly in a direction to project beyond the free end of the door 8.

The length of the cavity in the lining 20 is greater than the thickness ofthe lever 18, and its depth is sufficient to allow the lever to swing freely, except when the end is hearing against the rear wall of the lining or when the side of the lever near the end-is engaging against the front of the lining. In the first of these two positions the lever is employed to project the slide, and in the second position the lever is employed to retract the slide. In the first of the two positions the lever assumes a toggle-joint or knuckle-joint relation to the walls of the notch and exerts great force, and the load bearing against the inner surface of the door does not tend to jam or tighten the pin 23.

On the inside of the post 14 is a plate 21, bolted to the post and provided on that edge of it which lies toward the door-opening with a bent lip 22, that extends vertically from the top to the bottom of the plate 21 and forms a socket underneath the bent lip and between the lip and the post for the front edge of the plate 16, and this lip flares, so that the door will be forced to its place when the plate 16 is forced forward by the lever 18. The plate is extended or pushed to engage in the opening between the post and the plate 21 by closing the free end of the lever 18 in toward the door,and the lever is held in place when closed entirely by a pin 23, which slips through the hole 24: in ears 26 and through the hole 25 in the lever. I

The door is mounted in place by putting the door in the position it is to occupy before either the bottom or top of the rod 2 is secured inplace. The bottom socket, which holds the rod 2, is located with reference to the door and its hinges, and after the bottom socket has been located the top end of the rod 2 is properly secured. By taking this course in locating the parts which support the door it may be hung so as to close tightly along the floor andclose properly against the post.

A crowbar-socket 27 is placed midway between the ends of the door and at the bottom of it, so that the door may be forced up, sliding on the rod 2 and behind the plate 21.

The double pintle of the hinge by which the hinge end of the door is secured, the one pintle consisting of the rod 2 and the other pintle consisting of the pin 9, permits of great freedom in the action of the door in swinging. Nevertheless the door is swung with certainty to a position with its rear edge bearing against the post 13 and between that andthe rod 2, and yet it admits of an immediate withdrawal of the door forward from that position to enable it to swing either in or out.

At the corner 30 the metal of the slide 16 is cut obliquely for a short distance back from the vertical edge, and a pin 31 is driven into the post in a position to engage over the oblique edge. When the slide is forced out by the lever 18, it engages under the pin 31, and the door is held firmly down against the floor. The pin 31 is driven far enough back from the edge of the post to allow the door to slide up with the bar in engagement with the post.

The door can be raised a short distance, so as to leave a discharge-opening underneath it, and yet the door is held securely in place against the posts. This is a feature of great advantage where the unloading is done by men with shovels, as grain cannot be thrown out from the door-opening to so great a distance as to be scattered andwasted.

What I claim is- 1. In a grain-door, the combination of a door, a vertical rod arranged in proximity to a door-post, a double hinge arranged to turn -on the rod and on a pintle located at the opposite side of the door and to bring the door between the rod and the door-post, substantially as described.

2. In a grain-door, the combination of a door longer than the distance across the door- .opening, a rod arranged vertically beside the door-post on the side thereof toward the inside of the car and inside of the closed position of the door, a tube sleeved on the rod, a hinge having one leaf secured tothe tubeand one leaf secured to the door on the side thereof which lies toward the outside of the car when the door is closed, the leaf secured to 1 the tube being arranged to extend across the end of the door, means provided for an extension of the door, which .extensionisarranged .to bear against the door-post, substantially as described. i i

3. In combination with the door-p0st of a car, a rod arranged parallel thereto, a door arranged to engage between the post and the rod, and hinge connections arranged to turn on the rod and on a pintle intermediate the rod and door and to permit both swinging and horizontal sliding of the door, substan tially as described.

4. In combination with the door-post of a car, a rod arranged parallel thereto, a door arranged to engage between the post and the rod, a hinge slidingly connected with the rod,- secured to the door and arranged to engage across the end of the door, and between the door and the post and to take end thrust of the door, and with ahinge-joint between the rod and the door connection, whereby the door is adapted to have swinging motion on either the hinge-pintle or the rod, a horizontal reciprocating motion, or a vertical sliding motion, substantially as described.

5. In combination with a car-door, a Verti-' cal rod secured to the car and spaced there from to admit the door between the rod and the door-frame, a tube sleeved on said rod and bearing on the face of the door when the latter is closed, hinge-leaves secured to said tube, hinge-leaves secured to the door and pintle connectionsfor the hinge-leaves, substantially as described.

6. In combination with a car-door, a vertical rod secured to the car and spaced there from to admit the door between the rod and door-frame parallel with a door-post and at the side thereof inside the car, a tube arranged to slide on said rod and bearing on the face of the door when the latter is closed, hinge-leaves secured to the tube arranged to extend across the end of the door, angled hinge-leaves secured to the door on the side thereof toward the outside of the car and pineeaeve tle connections spaced froin the (1001' by the angled hinge leaves, substantially as described.

7. In combination with a car-door and an extension slidingly held thereto, a lever pivoted t0 the extension, a socket in the door having a bearing-face arranged to engage the end of the lever when the free end of the lever is swung against the face of the slide, and a bearing-face arranged to engage the lever near the end and at the side thereof when the lever is swung dut substantially to a right angle to the slide, said lever being free from actuating engagement with thesocket after it leaves its engagement with either bearing- 15 face until it engages the opposite bearing face.

In testimony whereof I sign this specification in the presence of two witnesses.
